Live tourney Structure, are these worth playing?

[ffbooj]

Several of the local cardrooms in my area have low buy in NLHE tourneys ($40-80). Most start you out with 5000 chips 25/25 blinds. But the blinds increase every 15 mins. and by the first break (1hour) they're at 200/400. These tourneys are usually limited to under 100 players. With this structure I am curious if they're even worth playing, it seems to me that they would be more of a card catching contest than a true test of someones skills. Any input would be appreciated.
